这里以搜索歌曲为例：
前端：
<view class="search">
<view class="search-bar">
<view class="search-wrap">
<icon type="search" size="16" class="icon-search" />
<input type="text" placeholder="请输入搜索内容" class="search-input" name="searchKeyword" bindinput="bindKeywordInput" value="{{searchKeyword}}" />
</view>
<view class="search-cancel" bindtap="keywordSearch">搜索</view>
</view>
<view class="search-result">
<scroll-view scroll-y="true" bindscrolltolower="searchScrollLower">
<view class="result-item" wx:for="{{searchSongList}}" wx:key="unique" data-data="{{item}}" >
<view class="icon{{item.isonly=='0' ? ' nocopyright' : ''}}"></view>
<text class="title">{{item.SongName}}--{{item.SingerName}}</text>
<view class="subtitle">
<text>{{item.SingerName}}</text>
</view>
</view>
<view class="loading" hidden="{{!searchLoading}}">正在载入更多...</view>
<view class="loading complete" hidden="{{!searchLoadingComplete}}">已加载全部</view>
</scroll-view>
</view>
</view>登录后复制
